SAD-IRON.

To all whom it may concern:

Be itknown that 1, CHARLES A. BEACH, a citizen of the United States, anda resident of the city of New York, borough of Brooklyn, county ofKings, and State of New York, have invented a new and 1111- provedSad-Tron, of which the following is a full, clear, and exactdescription.

The object of the invention is to provide a new and improved heatingstructure for sad-irons which may utilize at the will of the operator aplurality of sources of heat supplying fuel.

A further object of the invention is the arrangement in a sad-iron ofheating means formed to utilize a supply of gas and air furnished fromeither end of the iron.

A still further object of the invention is the arrangement of improvedburners for sad irons designed to utilize or burn a mixture of air andgas supplied from a suitable supply pipe or tube, and also for utilizing gas and air supplied from an ordinary Bunsen mixer, these meanssupplying the fuel being used at different times.

In carrying out the objects of the invention a heater is provided for asad-iron formed for permitting a single flame to be projected across theiron, the flame being supplied with fuel from a suitable source and ledinto the iron at one end. A. second supply of fuel is led into the ironat the opposite end and connected with the heater in such a manner as tobe directed in a plurality of jets toward the surface to be heated.Suitable piping and valves are provided so that either supply of fuelmay be used at any time, one supply being passed in at one end of theiron, and the other supply being passed in at the opposite end.

A practical embodiment of the invention is represented in theaccompanying drawings forming a part of this specification, in whichsimilar characters of reference in dicate corresponding parts in all theviews.

Figure 1 is a side view of an iron embodying the invention; Fig. 2 is alongitudinal vertical section through Fig. 1; and Fig. 3 is a bottomplan view of the heater arranged in an iron. Fig. 4 is a sectional vieWthrough Fig. 1 approximately on line 44:.

Referring to the accompanying drawings by numerals, 1 indicates the bodyof an iron with a bottom portion 2, a heat shield 3, and a handle 4t.The heat shield 3 is Specification of Letters Patent.

spaced from the upper part of the body 1, but rigidly connected theretoby securing means extending into lugs 4. The lugs a space the shield 8above the top of the iron for protecting the hand of the operator andalso accommodating a pipe hereinafter fully described.

The body 1 is formed hollow for accommodating burners 6 and 7. Theburners 6 and 7 are shown integral, which is the pre ferred form, but itwill be evident that the same may be made separate and connectedtogether if desired by suitable interlocking lugs or other means. Theburner 7 is formed with a bore 8 having a lateral extension 9 fordirecting fuel, as for instance air and gas, into the space 10. A screenof wire mesh 11 is provided in the usual man- 'ner for preventing, orassisting in preventing, the backfiring of the gas. The flames from theburners are deflected by plate 21 so as to heat the bottom 2. The burner7 is fitted in the front end ofthe body 1 of the iron and is adapted toreceive a pipe 13, which in turn is connected with an elbow 14L threadedon to the pipe 5. The pipe 5 is provided with a valve 15 so as tocontrol the air and gas from a pipe or tube 16 when the same is fittedover the pipe 17 and the valve 18 is closed. The pipe or tube 16 ispreferably flexible so as to permit a free movement of the iron and isconnected with a suitable supply of compressed air and gas for providinga proper mixture for supporting' combustion when the mixture escapesthrough the screen 11.

The burner 6 is preferably cast integral with the burner7, but may bemade independent thereof. This burner is provided with a substantiallyannular bore 19 communicating with a plurality of discharge apertures20. A central web or deflecting member21 is provided so as to deflectthe heat generated by the burners 6 and 7 in order that the same mayproperly heat the bottom 2 of the iron. It will of course be evidentthat although the major'por'tion of the heat is maintained adjacentbottom 2, some of the heat and the products of combus tion may pass outsuitable openings in the iron, as for instance openings 3. The productsof combustion passing from space 10 may pass upwardly through anydesired space, as for instance the space between the side walls of theiron and the burner 6. The

products of combustion are preferably re duced to a minimum as it isdesigned to supply a comparatively large quantity of an to as possibleunder the circumstances.

it will be evident that the end door 23 could be made independent of theburner 6, but

by having the door formed integral therewith, as shown, which thepreferred structure, and having the burner 7 formed integral with theburner 6, the pipe 13 will hold both of the burners and door 23 inposition. To positively prevent any movement of the door 23 orassociated parts, a pivotally mounted locking member 24 is providedwhich is designed to bear against the door when the iron is in use.Threaded into the enlargement 22 and in free communication with the bore19 is a pipe 25 connected with an ordinary Bunsen mixer 26. It will beunderstood that any kind of a mixer 26 may be used which will draw inair with the pure gas being used for mixing air therewith sutlicientlyfor supporting combustion in the space or chamber 10. The mixer 26 issup plied with gas from the pipe 27 which is connected with a tube 28.The tube 28 is in free communication with the pipe 17 so that when theValve 15 is closed and the flexible tube or pipe 28 is connected withpipe 17, is supplied. to the mixer 26, the valve 18 being open. Bymanipulating the valves 15 and 1S, and the tubes 16 and 28, a mixture ofair and gas may be used, or the pure gas may be used. It will also benoted that a supply of fuel is provided at each end of the iron. Thesubstitution of pipes 16 and 27, and the means for permitting thissubstitution, is of great advantage as in many institutions which usethe automatic heating iron it is desired to use the iron after theordinary power for supplying compressed air for pipe 16 has been turnedoft. When this power has been turned oil and consequently no air can besupplied to pipe 16 for mixing with the gas therein, the burner 7 willnot operate as there is not suliicicnt air in the chamber 10 to supportcomlmstion und or these circumstances. Then this occurs, the pure gas isturned on to pipe 27 and the Bunsen mixer 26 will cause a proper mixtureto be forced into the iron and to distribute it through the apertures20.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent:

1. In a self-heating sad-iron, a body portion, a pair of burnersarranged in said body portion connected together, one of said burnersbeing formed with a baflle for the burners and the second burner actingas a support for the burner formed with the bafie, a supply nipple orpipe and independently controlled connectors between said pipe and theburners.

2. In a self rhea-ting sad iron, a body portion, a pair of burnersarranged in said body portion, a supply pipe, means connected to saidsupply pipe for directing air and gas under pressure to one of saidburners, and a second means connected to said supply pipe for directinggas and air to the other of said burners, said last mentioned meansincluding a Bunsen mixer, said last men tioned burner being providedwith a battling member for confining the heat from both of said burnersto a position near the bottom of said body portion.

3. In a self-heatin sad-iron, a body portion, a pair of independentburners arranged in said body portion, said burners belng arranged atopposite ends of said body portion, a supply pipe, means connected tosaid supply pipe'for directing air and gas under pressure to one of saidburners. and means connected to said supply pipe including a Bunsenmixer for supplying a combustible mixture to the other of said burners,the latter burner being provided with a central deflecting web designedto deflect the flame from said burners toward the bottom of said bodyportion.

4. In a self-heating sad iron, a body portion, a pair of burnersarranged in said body portion rigidly secured together, one of saidburners being formed so as to direct a blaze therefrom substantiallyparallel to the bottom of said body portion, a deflecting web or ba-fliesecured to the other of said burners for deflecting the flame from bothof the burners in order to retain the same adjacent the bottom of saidbody portion, and independent means for sumalying a combustible mixtureto said burners.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
